Abstract:
Mining areas include production areas, the living areas for workers and their families, as well as local farmers. While mine-grain mixed zone refers to the compound area of main grain-producing areas and main producing areas of mineral resources, which not only ensures normal mining activities of mineral resources, but also ensures the output and quality of grain production. We could learn that there are difference between mining area and mine-grain mixed zone in definition. The mine and grain mixed zone has more complex function than mining area alone. Mining activities will produce exhaust gas, waste water, waste residue and other wastes that will pollute the atmospheric environment, water, and soils harmful to animal, plant and people in the area. In addition, the level of land use diversity in mine-grain mixed area production is higher than other areas such as sole mining, or farming area. From this view, the conflict of living, production and ecological space in mine and grain composite area is more serious. However, the extent of the living, production and ecological space conflict in mine-grain mixed area is not very clearly known at present. It may be affected by both the mining activities and grain production. All of these problems need to be studied. Therefore, the purpose of this paper is to study whether the gold mine area impacts on the spatial distribution of living, production and ecological space. Based on both the theory of AVC (attractive, vitality and capacity) and space function values ,we reconstructed the spatial distribution of living, production and ecological space, and realized the spatial optimization and coordinated development. During the process of optimization, we set a goal of building a habitability, suitable for tourism and suitable for industrial environment. And taking Xuguang township, Yiyang County, mine-grain mixed zone as the studied area, the space function value was calculated by adjusted value per unit area equivalent method, and we adjusted stroke of spatial layout based on the theory of AVC and space function values. The results showed that the mining area had certain negative effects on living, production and ecological space. Besides, the living, production and ecological space function value was inversely proportional to the distance from the mining area. In addition, the distribution of living, production and ecological space had the characteristics of minority concentration and most dispersion. While, both the function value of living, production and ecological space was improved and the spatial pattern was transformed from disorder to regulation after space reconstruction. In addition, the value of ecological space function increased from 23 587.22 ×104 yuan to 24 307.13×104 yuan.
